It fits the KX-TG2411, KX-TG5761, KX-5771, KX-5776, and over 145 additional KX-series handsets that share the HHR-P105 form factor. If your handset no longer holds a charge or drops calls mid-conversation, this is the correct replacement cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKX-TG and KX-5 series compatibility:\u003c\/strong\u003e\n    These handsets share a common 2.4V two-cell Ni-MH pack with the same connector orientation and physical footprint. The base station charges via a fixed-current contact pad — no proprietary handshake or BMS negotiation is involved, so the swap is straightforward.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a KX-TG2411 handset through charge and discharge on the base cradle. The cell accepted current from the first placement, and the charge indicator on the base lit within 30 seconds of seating the handset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH cordless packs:\u003c\/strong\u003e\n    After installing, place the handset in the base for a full 16 hours before using it off the cradle. Ni-MH cells shipped in partial-discharge state will not reach rated capacity on a shorter initial charge — expect the first two to three cycles to deliver less than full talk time before the pack stabilises.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge light after fitting a new Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePanasonic KX-series base stations use a simple voltage-sense circuit to confirm a battery is present before starting the charge cycle. A new Ni-MH cell that has self-discharged in storage can read below the base's acceptance threshold — typically under 2.0V — and the charge indicator stays dark. This is not a fault with the base or the battery. Place the handset firmly in the cradle, leave it undisturbed for 30 to 60 minutes, and the trickle current will raise the pack voltage enough for the base to switch into full charge mode.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset loses DECT pairing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery from a Panasonic KX-series handset cuts all power to volatile memory, which stores the pairing registration with the base station. On some KX models this causes the handset to show \"Register\" or display no base link after the new battery is installed. To re-pair, press and hold the FIND or LOCATE button on the base for three seconds, then follow the registration prompt on the handset. The process takes under two minutes and restores full DECT functionality without a factory reset of the base.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340102860890,"sku":"BWCS-P105CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340102893658,"sku":"BWCS-P105CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340102926426,"sku":"BWCS-P105CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P105CL_1.webp?v=1778367188","url":"https:\/\/batteryweb.com\/products\/panasonic-kx-tg2411-replacement-battery-24v-850mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
